Problem with nmon, actual CPU usage per process

Yes, that's correct.
Where I currently have a doubt is, that I have no process, that is running a long time yet, but having a peak at the moment so that I can see that the values tprof shows are relevant for the interval and not again just some kind of average etc.
When I have a infinite loop running, it will be at a certain level for all of it's life span. So I can't tell if the output is because of the actual CPU usage in the interval or just the average, since it was always at this level.
I checked boxes in my environment, that have some amount of traffic, but sadly the involved processes have a very jumpy behaviour about CPU usage and are so with not suitable for my test to proof the output of tprof.
If you have such processes, that are running for some hours or days etc. already, you could check that for me, if you like

Hi,
I am designing a load balancer for an application. I am trying to find out the CPU usage by a specifc Unix process (PID is known). I guess I can use ps command to find that. can somebody help me in finding what exact command I should use to find? It is on AIX 5.3.

Hi,
I have a shell script. But, upon execution of the same, the cpu usage is sometimes getting 100 % (checked executing top command).

My concern is, is there any default method, by which I can check... (1 Reply)

tswtclmt - Time Sliding Window Three Conformance Level Meter DESCRIPTION
The Time Sliding Window Three Conformance level meter (tswtcl) meters a traffic stream and determines the conformance level of its packets. Packets are deemed to belong to one of the three levels, Red, Yellow or Green, depending on the committed and peak rate. The meter provides an estimate of the running average bandwidth. It takes into account burstiness and smoothes out its estimate to approx- imate the longer-term measured sending rate of the traffic stream. The estimated bandwidth approximates the running average bandwidth of the traffic stream over a specific window (time interval). tswtcl estimates the average bandwidth using a time-based estimator. When a packet arrives for a class, tswtcl re-computes the average rate by using the rate in the last window (time interval) and the size of the arriving packet. The window is then slid to start at the current time (the packet arrival time). If the computed rate is less than the committed configuration parameter, the packet is deemed Green; else if the rate is less than the peak rate, it is Yellow; else Red. To avoid dropping multiple packets within a TCP window, tswtcl probabilistically assigns one of the three conformance level to the packet. STATISTICS
The tswtcl module exports global and per-class statistics through kstat: Global statistics: module: tswtclmt instance: <action id> name: tswtclmt statistics class <action name> green_bits <number of bit in green> green_packets <number of packets in green> red_bits <number of bits in red> red_packets <number of packets in red> yellow_bits <number of bits in yellow> yellow_packets <number of packets in yellow> FILES
